Error description
Using IBM Developer for z Systems v14.1.3 a coordination problem in the routines that figure out who owns MVS file locks can cause slow WRITE and READ during the SAVE process. In parallel, we can notice the lack of timeout indicators and missing information in DISPLAY PROCESS and DISPLAY CLIENT operator commands. If two users on the same threadpool attempt to query MVS file lock owners at approximately the same time, one of them will suffer a 10 second delay. This lock owner query processing is called when retrieving the attributes for the file, which occurs frequently. This is relevant when two users attempt to edit files nearly simultaneously. This intermittent error also causes the general timeout threadpool and slow response to the operator DISPLAY commands. Moreover, we find that timeout indicators and information may be missing in DISPLAY PROCESS and DISPLAY CLIENT operator commands
Local fix
Decreasing the Maxclient value to 7 has stopped the problems
