All Errors

The "ERR max number of clients reached" error occurs when the number of active client connections exceeds Redis's configured maxclients limit (default 10,000). Common causes include connection leaks, insufficient connection pooling, and undersized Redis instances. Fix by using connection pooling, increasing maxclients, upgrading your Redis instance, or reducing connection usage.

The Redis error "ERR value is not an integer or out of range" occurs when integer operations (INCR, DECR, INCRBY, HINCRBY, etc.) receive invalid values. This happens when the stored value is not a valid integer, exceeds 64-bit signed integer limits, or is a floating-point number. Fixing requires storing valid integers, using INCRBYFLOAT for decimals, or validating input before operations.

MySQL Error 1064 (ER_PARSE_ERROR) occurs when the database parser encounters invalid SQL syntax. Common causes include misspelled keywords, unescaped reserved words, mismatched quotes or parentheses, missing data values, and outdated syntax. Fixing requires careful review of the query, using backticks for reserved words, and validating syntax with tools.

PostgreSQL terminates connections unexpectedly due to server crashes, network timeouts, or configuration issues. Fix by checking server logs, enabling TCP keepalives, and verifying network stability.

The "ERR timeout reading from client" error occurs when Redis cannot read a command or response from a client within the configured timeout period. This commonly happens with long-running Lua scripts, slow commands, network issues, or misconfigured timeouts. Fixing requires optimizing scripts, adjusting timeout values, and investigating network conditions.

This error occurs when a Redis command is executed on a key that holds a different data type than expected. Redis enforces strict type checking—using LPUSH on a string key or HGETALL on a list will fail. Fix by checking the key type with TYPE, using the correct command for that type, or deleting and recreating the key with the proper data type.

This error occurs when PostgreSQL cannot find a table, view, or other relation with the specified name. It's usually caused by schema issues, case sensitivity problems, typos, or incorrect database connections. Fix by verifying the table exists, checking exact naming and case, specifying the correct schema, or adjusting search_path settings.

This fatal error occurs when PostgreSQL cannot allocate enough memory to execute a query or operation. Common causes include undersized work_mem settings, high concurrent connections, inefficient queries, and insufficient system RAM.

This error occurs when a Redis command is blocked by authentication, ACL permissions, or replica mode restrictions. It typically happens when credentials are missing, user permissions are insufficient, or you're trying to write to a read-only replica.

Redis has RDB persistence enabled but cannot write snapshots to disk, blocking write operations. This typically indicates disk space, permission, or memory issues preventing background saves.

This error occurs when your application attempts a write operation on a Redis replica instead of the primary master node. Redis replicas are read-only by default to prevent accidental data corruption.

This error occurs when a MySQL query references a column name that doesn't exist in the table or isn't accessible in the current query context. It's one of the most common SQL errors and usually results from typos, missing quotes around string values, or incorrect table aliases.

Fix Git's "fatal: couldn't find remote ref" error caused by deleted, renamed, or stale branch refs. Run git fetch --prune and check the exact branch name.

Fix Git's "error: remote origin already exists" by updating the URL with git remote set-url origin, or removing it via git remote remove origin and re-adding.

The Prisma P1010 error indicates that the database user lacks the required permissions to perform operations, typically during migration or connection initialization. This usually occurs due to insufficient CREATE DATABASE privileges for shadow databases or incorrect connection credentials. Resolving it requires granting proper database permissions or configuring a shadow database URL.

The shard iterator used to read DynamoDB Streams has expired after 15 minutes of inactivity. You need to obtain a fresh shard iterator before making subsequent GetRecords requests.

This error occurs when Prisma Pulse cannot establish a connection to your database server, typically due to network issues, incorrect connection strings, firewall restrictions, or database unavailability. Resolving connectivity is essential for enabling real-time subscriptions.

Fix Git's "pathspec did not match any file(s)" error caused by typos, untracked files, or unfetched branches. Step-by-step checks and fixes.

This error occurs when your Prisma Accelerate project exceeds the included query limit on your current pricing plan. It only occurs on the free tier when you hit the 60,000 monthly queries limit.

This error occurs when attempting a point-in-time restore in DynamoDB with a restore timestamp that falls outside the valid recovery window. The specified restore time must be between EarliestRestorableDateTime and LatestRestorableDateTime, which is typically the last 35 days but always excludes the last 5 minutes.
