Question & Answer
Question
You are running a large number of clients against an IBM MQ queue manager in Linux and you want to know why there are FDC files showing resource shortage:
probeid XC035040 from pthread_create.
probeid XC035040 from pthread_create.
An example of the FDC is:
| Probe Id :- XC035040
| Component :- xcsCreateThread
| Program Name :- amqrmppa
| Major Errorcode :- xecF_E_UNEXPECTED_SYSTEM_RC
| Probe Description :- AMQ6119: An internal WebSphere MQ error has occurred
| ('11 - Resource temporarily unavailable' from pthread_create.)
| Arith1 :- 11 (0xb) | Comment1 :- '11 - Resource temporarily unavailable' from | pthread_create.
.
Sometimes, there is an additional entry:
| Probe Id :- ZS401010
| Component :- zstStartAsyncConsumeThread
| Major Errorcode :- xecP_E_PROC_LIMIT
| Probe Description :- AMQ6026: A resource shortage prevented the creation of a WebSphere MQ process.
| Component :- xcsCreateThread
| Program Name :- amqrmppa
| Major Errorcode :- xecF_E_UNEXPECTED_SYSTEM_RC
| Probe Description :- AMQ6119: An internal WebSphere MQ error has occurred
| ('11 - Resource temporarily unavailable' from pthread_create.)
| Arith1 :- 11 (0xb) | Comment1 :- '11 - Resource temporarily unavailable' from | pthread_create.
.
Sometimes, there is an additional entry:
| Probe Id :- ZS401010
| Component :- zstStartAsyncConsumeThread
| Major Errorcode :- xecP_E_PROC_LIMIT
| Probe Description :- AMQ6026: A resource shortage prevented the creation of a WebSphere MQ process.
Cause
- MQ sets the error code xecP_E_PROC_LIMIT when pthread_create or fork fails with EAGAIN.
- MQ sets the error code xecP_E_NO_RESOURCE when pthread_create or fork fails with ENOMEM.
