We're experiencing strange behaviour on our PI 7.4 SP5 dual-stack production (unfortunately) system.
Upon adding a certificate into STRUSTSSO2, the ABAP stack loses contact with the Java stack, causing connections to fail and the system to become unusable. At this point a reboot brings up the ABAP stack okay, but we get:
ERROR => Java node 'server0' terminated with exit code 2150
in the dev_server0 file and the Java stack does not start. At this point the only way (that I've been able to discover) to get the system back is to restore the /usr/sap/SID/D*/sec/*.pse files and do a database restore (which thankfully, being PI, does not take a long time).
This has happened twice now and the only things that I can think of that are consistent with both times are that
1) I've put a certificate in
2) the system has been under reasonably heavy load
Er, anyone experienced this? Is restarting the ICM a bit flaky in a busy system? Memory issues? Where would the problem lie?
The only thing I can think of trying is to reboot the system, put the certificate in (when nothing else is happening on the system), then maybe bounce the system again...
