(status info truncated)[2023-09-04T09:17:03.826000] [COM-89] [I] Internal Error with condition 'IS_VALID_TID(target_id)' (1 args) (bitqueue.c:316:bitq_write_with_args) (pid=14264, sessid=89, tid=89)

 

Cause

During the deadlock detection process, an attempt was made to access the bitq (bit queue) with an invalid TID, causing this internal error.
 
 

Solutions

Apply the patch to resolve the issue. (Applied patch: FS06_CS_201350b)
  • The FS06_CS_201350b patch is a fix that modifies unstable parts related to the null terminator of snprintf to prevent buffer overrun in Windows environments.
