You should increase the value of recDynLinkQsize.

Hi,
I've been working on EPICS pid ioc for temperature control, that uses Wiener power supply and Keithly 3706A PT1000 sensors scanner.
Recently we updated RHEL8.5 kernel, and I noticed that ioc shows errors since end of April 2022. Update might not be related to OS update. I might also be missing something in the dependency. Perhaps
someone observed this before.
## EPICS R7.0.6
## Rev. R7.0.6
OS: RHEL8.5
During ioc startup, getting error messages from
sscan: / recDynLink.c : 549
precDynLink->onQueue++;
if (epicsMessageQueueTrySend(recDynLinkOutMsgQ, (void *)&cmd,
sizeof(cmd))) {
errMessage(0,"recDynLinkPut: epicsMessageQueueTrySend error");
status = RINGBUFF_PUT_ERROR;
precDynLink->onQueue--;
}
calc: / swait.c : 838/840
recDynLinkGet(precDynLink, &monData, &nRequest,
0, 0,
0);
if (swaitRecordDebug>5)
errlogPrintf("swaitRecord(%s)inputChanged: queuing monitor on
%d =
%f\n",pwait->name,index,monData);
if (epicsRingBytesPut(pcbst->monitorQ, (char *)&index,
sizeof(char))
!= sizeof(char))
errMessage(0,"recWait rngBufPut error");
if (epicsRingBytesPut(pcbst->monitorQ, (char *)&monData,
sizeof(double))
!= sizeof(double))
errMessage(0,"recWait rngBufPut error");
if (swaitRecordDebug>5) {
errlogPrintf("swaitRecord(%s)inputChanged:
%d entries left in monitorQ\n",
pwait->name,
(int)(epicsRingBytesFreeBytes(pcbst->monitorQ)/sizeof(struct qStruct)));
}
calc: / swait.c: 870/872
if (!swaitRecordCacheMode) {
if (epicsRingBytesGet(pcbst->monitorQ, (char *)&inputIndex,
sizeof(char))
!= sizeof(char))
errMessage(0,
"recWait: rngBufGet error");
if (epicsRingBytesGet(pcbst->monitorQ, (char *)&monData,

!= sizeof(double))
errMessage(0,
"recWait: rngBufGet error");

===================
After ioc boots, the messages stop.
Thanks for the help!
