SAPLHTTP_RUNTIME - loong running and loop process
We are getting an issue with our PI 7.1 Test system due to long running and
never ending loop of SAPLHTTP_RUNTIME program that is causing TIME_OUT
short dump (Please refer to below short dump).
And after the process was cancelled, in several minutes, there will be
another same process until ended with short dump, it looks like an
never ending loop.
Need your help in case you already had this kind of experiences. We've already rebooted the system but the issue still persists.
The system profile contains the maximum runtime of a program.
When this time limit has been exceeded, the program is terminated
to make way for other users who may be waiting.
In the case of a work area, this means that
- endless loops (DO, WHILE, ...),
- database accesses producing an excessively large result set,
- database accesses without a suitable index (full table scan)
do not block the processing for too long.
The maximum runtime of a program is limited by the system profile
parameter "rdisp/max_wprun_time". The current setting is 1800 seconds. After
this limit has
been exceeded an attempt is made to interrupt the SQL statement running
or to tell the ABAP processor to interrupt the current program. A
maximum of 60 seconds is then waited. If after this time the program is
still active then the work process is restarted.
