SAP Uprocs fail after a restart of the SAP systems.
After analysis, the Manager for SAP (uxagtsap) crashes generating a core file at that time, being this the reason for the Uprocs to fail.
The following kind of errors appear in universe.log:
*** glibc detected *** ./uxagtsap: double free or corruption (fasttop): 0x00000000007cb850 ***
*** glibc detected *** ./uxagtsap: malloc(): memory corruption: 0x00007fb5540293d0 ***
Issue only detected on Linux / Unix servers
