Informix Error -25594
-25594 Shared Memory client failed to alert the database server for service.
There are two possible reasons for this error:
If the error number is zero, the problem is memory corruption.
If the error number is not zero, an operating system call failed, usually because a semaphore operation could not be performed.
Report the problem to the system administrator, who should restart the database server or restart the computer. In either case, call IBM Support. For operating system call failure, Support might advise you to set the environment variables IFX_SEMOP_INTERVAL or IFX_SEMOP_RETRY.
