Title:
'assert (size <= ntohs ( pMsg->m_postsize ))' failed in ..caserverio.c
line 344
Status in EPICS Base:
Invalid
Bug description:
From Chen Zhi-chu,
I've written an ioc (using TekVISA from Tektronix on a DPO7054 Oscilloscope, Windows XP) and it starts okay at first. But when it runs for like several minutes, I got an error like:
==============================================================
A call to "assert (size <= ntohs ( pMsg->m_postsize ))" failed in ..caserverio.
c line 344.
EPICS Release EPICS R3.14.5 $R3-14-5$ $2004/02/04 20:45:33$.
Current time Fri Sep 07 2007 09:49:29.518463915 .
Please E-mail this message to the author or to [email protected]
Calling epicsThreadSuspendSelf()
==============================================================
then it stunks. I suppose that the cas_commit_msg function checks the pMsg->m_postsize and finds out it's larger than size. But I don't know how these variables come from.
I'm sorry I'm just new to EPICS and have few experiences about C
programming. Could any of you give me a clue that what's happening
now? Any input is welcome.
