sadc and flock

[Grant Grundler <grundler@parisc-linux.org>]

Hi all,
I was getting cron job output from /usr/lib/sysstat/sa1 script.
The error was something like "flock: resource not avaiable".

I added one line to /usr/lib/sysstat/sa1:
  DFILE=/var/log/sysstat/sa${DATE}
  cd ${ENDIR}
+ lsof ${DFILE}
  if [ $# = 0 ]
  then
...

And now maybe 10-20 times per day (not every 5 minutes), I get
lsof output showing sadc is still running and has $DFILE locked:

COMMAND  PID USER   FD   TYPE DEVICE   SIZE   NODE NAME
sadc    1935 root    3u   REG    8,3 553200 194410 /var/log/sysstat/sa08

Any recent changes cause sadc to run longer than 5 minutes now?
Or is this likely some parisc-linux kernel bug?
(ie dropped signal or some such)

This is a C3600 (550Mhz PA8600), "testing" release:

/var/opt contains a full debian mirror + public RH/SuSE bits.
