Error -908 ??

Hi Gurus, I'm using synonyms of table belonging to another informix server (same machine). When trying to select a statement with this synonym I have in a production environment, error -908 with conerr=-25580 ,oserr=32 1) where can i find information on those conerr and oserr because error informix guide don't explain this In fact this error has occured because the other informix server was down. In fact in log, i've found such assert that has occured twice in two months on exactly the same line (rsinit.c and mt.c) Do you ether encounter such problem ??????? Teh first time it occured we increment unix number of semaphore along with NUMAIOVPS value ?????? 09:16:13 Assert Failed: Internal Error - Segmentation Violation 09:16:13 Who: Session(18880, gladm@hpat502, 1195, -876637544) Thread(18985, srvinfx, cbbd8418, 1) 09:16:13 Results: OnLine must abort 09:16:13 Action: Reinitialize shared memory 09:16:13 See Also: /opt/informix/dump/af.4a29019d 09:16:14 rsinit.c, line 10168, thread 18985, proc id 1234, Segmentation Violati on. 09:16:14 Assert Failed: Segmentation Violation 09:16:14 Who: Session(18880, gladm@hpat502, 1195, 0) Thread(18985, srvinfx, 0, 1) 09:16:14 Results: Fatal Internal Error requires system shutdown 09:16:14 Action: Restart OnLine 09:16:14 See Also: /opt/informix/dump/af.4a29019d 09:16:14 rsinit.c, line 10168, thread 18985, proc id 1234, Segmentation Violati on. 09:16:14 PANIC: Attempting to bring system down 09:16:14 mt.c, line 1205, thread 0, proc id 1243, semop: errno = 36 . 09:16:14 mt.c, line 1205, thread 0, proc id 1242, semop: errno = 36 . 09:16:14 Assert Failed: semop: errno = 36 Thank you very much for your help Best Regards PGI
