Version: 3.11.2
OS: ubuntu 12.04

What I know is that pmdalinux stops working in it just hangs as a zombie:

pcp      27674  0.3  0.0  51696  2172 ?        Ss   10:46   0:00 /usr/lib/pcp/bin/pmcd
root     27677  9.3  0.0      0     0 ?        Z    10:46   0:08  \_ [pmdalinux] <defunct>

It stops working after being asked by script similar to pcp2graphite (but a nagios one) for most available metrics.
Not sure how to debug it. Logs and strace do not say much. Nothing under gdb, but maybe I'm using it in the wrong way (just db /var/lib/pcp/pmdas/linux/pmdalinux - it exits after a moment).
