Help about server which hangs during restart

Hi. Once - when we tried to bring a database online after we had shut it down without problems as a part of a weekly task- database hung out for about an hour. Online.log looked like this: 08:19:13 On-Line Mode 08:19:13 Affinitied VP 1 to phys proc 4 08:27:11 VP Notify mechanism incomplete after 5minutes. This can be due to slo w network file access. Will try 12 more times 08:35:11 VP Notify mechanism incomplete after 5minutes. This can be due to slo w network file access. Will try 11 more times 08:43:09 VP Notify mechanism incomplete after 5minutes. This can be due to slo w network file access. Will try 10 more times 08:51:08 VP Notify mechanism incomplete after 5minutes. This can be due to slo w network file access. Will try 9 more times After that, database crashed, and online.log showed: 09:54:56 notifyvp(): vp 3, pid 22717 of class 0didn't rcv 09:54:56 notifyvp(): vp 4, pid 22718 of class 0didn't rcv 09:54:56 notifyvp(): vp 5, pid 22719 of class 0didn't rcv 09:54:56 notifyvp(): vp 6, pid 22720 of class 0didn't rcv 09:54:56 notifyvp(): vp 7, pid 22721 of class 0didn't rcv 09:54:56 notifyvp(): vp 8, pid 22722 of class 0didn't rcv 09:54:56 notifyvp(): vp 9, pid 22723 of class 0didn't rcv 09:54:56 Assert Failed: mt_notifyvp timed out 09:54:56 IBM Informix Dynamic Server Version 9.40.FC7 09:54:56 Who: Session(1, informix@orion, 0, 35930e028) Thread(7, main_loop(), 3592cc028, 1) File: mt.c Line: 11121 09:54:56 stack trace for pid 22637 written to /respaldo2/informix/tmp/siisa/af.3ef58cf 09:54:56 See Also: /respaldo2/informix/tmp/siisa/af.3ef58cf, shmem.3ef58cf.0 09:56:12 Error writing '/respaldo2/informix/tmp/siisa/shmem.3ef58cf.0' errno =28 09:56:12 mt.c, line 11121, thread 7, proc id 22637,mt_notifyvp timed out. 09:56:14 The Master Daemon Died 09:56:15 PANIC: Attempting to bring system down We finally were able to bring informix online only by restarting the entire server (a Sun server with Solaris 9). Even so, I'd like to ask you which is the reason why this kind of error happens. I'm talking about an informix 9.40 FC7 database.
