I've got a problem on our company AS/400
We're using the 570 with OS version V5R3
The users are getting into the system through iSeries emulator(Telnet) and some web interface product
(ABL, Webface, etc)
Starting this 2 weeks sometimes a number of users will get the session hang up. Some users are having the sessions hang up when signing on to the AS/400 with emulator.
checking the Jobs in QINTER, some of them are showing Lock waiting (LCKW).
And there are some messages in the QSYSOPR message queue showing "Unable to obtain lock on device XXXXXX", "All jobs at work station XXXXX ended", which XXXXX is the session job names.
Normally it last to about 1 minutes. And our jobs Interactive delay (QINACTITV) is 30s.
The Network engineer said there is no interruption on the AS/400 network at the moment and we are now having no idea on what happened.
Anyone has the related experience and any advice on the problem?
