Package: libnss-ldapd Version: 0.5+b1 Severity: important On my AMD64 box the nslcd demon crashes quite frequently.
After the crash no mappings are resolved any more as far as they are fetched from the LDAP server in the LAN. Local mappings still work. Those crashes occur about ten to twenty times a day without any visible action, although I was not able to find a way to reproduce the crash reliably: [EMAIL PROTECTED]:/var/log# grep nslcd.*segfault syslog.0 Feb 3 08:19:10 sofa kernel: nslcd[5358]: segfault at ffffffffac0008c0 rip 0000000000408eb0 rsp 0000000041000f70 error 4 Feb 4 05:44:37 sofa kernel: nslcd[18186]: segfault at ffffffffac00af90 rip 000000000040b6ee rsp 0000000041801b60 error 4 Feb 4 05:44:44 sofa kernel: nslcd[18234]: segfault at ffffffffac00af90 rip 000000000040b6ee rsp 00000000407ffb60 error 4 Feb 4 05:50:02 sofa kernel: nslcd[18745]: segfault at ffffffffac000a50 rip 0000000000408eb0 rsp 0000000041000f70 error 4 Feb 4 06:09:23 sofa kernel: nslcd[21479]: segfault at ffffffffac00b350 rip 00000000004041f6 rsp 0000000041000630 error 4 Feb 4 06:10:01 sofa kernel: nslcd[21563]: segfault at ffffffffac00b150 rip 0000000000408eb0 rsp 0000000041801f70 error 4 Feb 4 06:25:02 sofa kernel: nslcd[22085]: segfault at ffffffffac000a20 rip 0000000000408eb0 rsp 0000000042002f70 error 4 Feb 4 06:35:02 sofa kernel: nslcd[24194]: segfault at ffffffffac003d00 rip 0000000000408eb0 rsp 00000000407fff70 error 4 Feb 4 07:25:02 sofa kernel: nslcd[28654]: segfault at ffffffffac0009c0 rip 0000000000408eb0 rsp 0000000042803f70 error 4 Feb 4 07:35:01 sofa kernel: nslcd[32760]: segfault at ffffffffac001c20 rip 0000000000408eb0 rsp 0000000041000f70 error 4 Feb 4 07:39:01 sofa kernel: nslcd[1077]: segfault at ffffffffac00b150 rip 0000000000408eb0 rsp 0000000041000f70 error 4 The backtrace of the coredump is as follows: #0 0x0000000000408eb0 in ??
