Shutting down a stalled giomgr process on UNIX or Linux
If a giomgr process is hung or stalled, use the operating system commands to determine the ID of the hung process, then kill it.
Identify the process ID (PID) of the stalled ArcSDE service or giomgr process using the ps -ef command that was piped through grep to isolate the giomgr process.
ps –ef | grep giomgr arcsde 3403 1 0 06:00:03 ? 0:03 /prod/sdeexe/bin/giomgr /prod/sdeexe
Type the kill command. Include the PID to terminate the giomgr process.
kill –9 3403
