Cause type:
Configuration
Root Cause: This issue could be related to the file descriptor limit of the SAP manager process owner and the available memory to the SAP manager process.
Resolution:
To fix this issue:

1 - Stop the SAP Manager (in case of is still running),
2 - Using the 'ulimit' command, set the value to 'unlimited' for the 'data' : ulimit -d unlimited
Double check that this change has been taken in account with the command : ulimit -a
The concerned user is the owner of the SAP manager process.
3 - Edit the file 'uxstartjcs.ksh' and add the following environment variable, for example:
export LDR_CNTRL=MAXDATA=0x40000000
nohup $UXEXE/uxagtsap ${AREA} ${UCOMPANY} ${UNODE} > $UXSAP/log/univmgr_${UCOMPANY}_${UNODE}_${AREA}.log 2>&1 &
unset LDR_CNTRL
Remark : the value 0x40000000 corresponds to a data segment of 1G.
4 - Restart the SAP Manager in using the command 'uxstartjcs.ksh'.
