MaxDB does not start anymore

[Former Member]

Hello

I just restarted a server (with a SAP installation) and I have no access to the MaxDB.

x_server seems to be started correctly:

saps0a:s0aadm 8> x_server
2012-05-11 11:37:17  5856 INF  12916          Found running XServer on port 7200
2012-05-11 11:37:17  5856 INF  13011            version 'U64/LIX86 7.8.01   Build 014-121-233-288'
2012-05-11 11:37:17  5856 INF  13010            installation S0A  - path: /sapdb/S0A/db
2012-05-11 11:37:17 32160 INF  12916          Found running sdbgloballistener on port 7210
2012-05-11 11:37:17 32160 INF  13011            version 'U64/LIX86 7.8.01   Build 014-121-233-288'

But if I try to connect the DB:

dbmcli -d S0A -u control,[PASSWORD]

a process for each try is started that use the whole CPU:

   PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 6136 sdb       20   0 34156 4112 2880 R 99.9  0.1   7:12.63 dbmsrv
 7102 sdb       20   0 34052 3732 2508 R 99.9  0.1   4:37.36 dbmsrv

[The whole cmd is /sapdb/S0A/db/pgm/dbmsrv -sdbstarter 501 502 A -P 00000006000000090000000a0000000d]

Any idea would be appreciated.

Thank you and regards,

Tommaso

1) 
stop all processes dbmsrv
2)
cd /var/lib/sdb/dbm/ipc
mv S0A.dbm.shi S0A.dbm.shi.old
mv S0A.dbm.shm S0A.dbm.shm.old
