VALGRIND: Major impact on authentication!

Hi, I did run "valgrind radiusd -xxx" at Wed Feb 7 19:15:08 2007 and at Wed Feb 7 20:59:04 2007 radiusd DIED. Afterwards, "service radius restart" would not work and of lots of "Error: Internal error processing module entry", "Error: rlm_sql_oracle: fetch failed in sql_fetch_row: ORA-24338: statement handle not executed", and "Error: rlm_sql (sql): failed after re-connect" appeared. I've just disabled accounting in the NAS and then "service radiusd start" worked. Last messages (I have the entire log, 70MB, if you want): Wed Feb 7 20:59:04 2007 : Debug: radius_xlat: 'UPDATE radacct SET AcctStopTime = TO_DATE('2007-02-07 20:56:41','yyyy-mm-dd hh24:mi:ss'), AcctSessionTime = '0', AcctInputOctets = '0', AcctOutputOctets = '0', AcctTerminateCause = 'User-Request', AcctStopDelay = '21', ConnectInfo_stop = '' WHERE AcctSessionId = 'erx GigabitEthernet 11/0.109:2109:0021188786' AND UserName = 'fiba@foobar.com' AND NASIPAddress = '10.10.1.2' AND AcctStopTime IS NULL' Wed Feb 7 20:59:04 2007 : Debug: rlm_sql (sql): Reserving sql socket id: 19 00000000 65746D6F 6F632E6C 72622E6D 4E412027 44432044 49544953 31203D20 444E4120 00000000 50545320 45504F47 203D2052 20275327 20444E41 4C425453 4555514F 3D204F49 00000000 274E2720 44524F20 42205245 64692059 00000000 00000000 202068E0 00000000 00000000 04A238D4 00000000 63726573 65746D6F 6F632E6C 72622E6D 04A238DF 00000000 00000000 72677265 2E70756F 00000000 00000000 203D2065 67646172 70756F72 6C706572 00000000 72472E79 4E70756F 20206320 00000000 Argument/Register addr=be20748.
