RPC Errors and Warnings: Troubleshooting Network Issues

RPC errors and warnings are messages that indicate issues with the Remote Procedure Call (RPC) protocol. The RPC protocol is used to enable communication between different processes on a network. An RPC error or warning message might indicate a problem with the network connection, a misconfigured RPC server or client, or other issues related to the RPC protocol. In the examples given, the errors and warnings include failed attempts to send or receive data, connection errors, and attempts to retry requests that have failed. These messages are useful for troubleshooting network issues and identifying the source of problems with RPC communications.

Here are some of the common RPC errors and warnings:

• 'RPC error shell 0x7f216c740b90 0x4e53e,failed to send , msgLen:88 written:-1,reason:Transport endpoint is not connected': This error indicates that the RPC client is unable to establish a connection to the RPC server. The reason for this error could be a network issue, a firewall blocking the connection, or a misconfigured RPC server.
• 'RPC probe 0x5a0 recv probe msg and do response.ret=0': This message indicates that the RPC client has received a probe message from the RPC server. This is a normal message and does not indicate an error.
• 'PRC WARN TSC 0x54989,connection error.retry to send request again.numOfTry=1 msgType=43': This warning indicates that the RPC client has encountered a connection error while attempting to send a request to the server. The client will retry sending the request. The 'numOfTry' value indicates the number of times the client has attempted to send the request.
• 'UTL cache:stable-vgroup-list will be cleaned up': This message indicates that the cache for the 'stable-vgroup-list' data is being cleaned up. This is a normal operation and does not indicate an error.
• 'rpc error deep tcp send data failed(chandle null). data=0x0x7f8b911aca10 len=88 ip=0x0 port=0': This error indicates that the RPC client failed to send data to the server. The reason for this error could be a network issue or a problem with the TCP connection.
• 'rpc probe 0x20f recv probe msg and do response.ret=0': This message indicates that the RPC client has received a probe message from the RPC server. This is a normal message and does not indicate an error.
• 'rpc error shell 0x7f8b9125e590 0x384c1, failed to send,msgLen:88 written:-1,reason:Success': This message indicates that the RPC client failed to send data to the server. The reason for this error could be a network issue or a problem with the TCP connection.
• 'warn tsc 0x54992 connection error.retry to send request again . numOfTry=1 msgType=43': This warning indicates that the RPC client has encountered a connection error while attempting to send a request to the server. The client will retry sending the request. The 'numOfTry' value indicates the number of times the client has attempted to send the request.
• 'warn tsc 0x54992 connection error.notify client query over.numOfTry=2 msgType=43': This warning indicates that the RPC client has encountered a connection error while attempting to send a request to the server. The client will notify the client that the query is over. The 'numOfTry' value indicates the number of times the client has attempted to send the request.
