but I don't know what Jenkins was doing at the time.
I'm using 1.399 ; I've not had a chance to update to 1.400 (or even check how stable it is)
I've only seen this once, however. It does not happen repeatedly. I've been using 1.399 since it was released

added a comment - Long shot but David, did you ever figure out the cause of this "pam" issue? I'm seeing the same org.jvnet.libpam.PAM.authenticate jvm crash, though unrelated to jenkins. Java 7 on CentOS 6.4.

added a comment - I think the root bug is in a standard RedHat/CentOS 6 PAM module related to finger print scanners. Fix with "yum remove fprintd-pam". For repro see: https://github.com/kohsuke/libpam4j/issues/8.

I've had this exception occur several more times, including when we upgraded to Jenkins 1.401.
It was impacting us seriously, so I disabled PAM authentication and switched Jenkins to use its own user database.
However, I'd prefer to go back to Linux /etc/passwd authentication if this can be fixed.
