SAP Sybase ASE Unable to shutdown with there are not enough ‘user connections’ Error: 1601, Severity: 17, State: 3

If you’re trying to shutdown ASE and you’re not able to log in to the ASE instance, you can shutdown the instance with “kill -15 ” on Linux/Unix:

server  Error: 1601, Severity: 17, State: 3
server  There are not enough 'user connections' available to start a new process. Retry when there are fewer active users, or ask your System Administrator to reconfigure ASE with more user connections

Obtain the os PID simply by running showserver:

$ showserver
USER          PID %CPU %MEM   SZ  RSS    TTY STAT    STIME  TIME COMMAND
sybase    542123 15.1  1.0 52220 93356  pts/2 A    11:15:35  8:34 /sybase/ASE-15_0/bin/dataserver -d/dev/rmaster -e/sybase/ASE-15_0/install/errorlog -c/sybase/ASE-15_0/sybase.cfg -isybase -ssybase -M/sybase/mem 

Kill the dataserver process with “kill -15” triggering a “shutdown with nowait” within ASE:

$ kill -15 542123

Only as a last resort, use “kill -9”.

  • If you need to, verify with “ipcs -m” that the shared memory segments are released, if not use “ipcrm” to release it.
  • Verify with “netstat -an |grep ” that the bound port(s) that ASE uses are released. If not, you may need to restart the machine to release them.
