[Sshguard-users] Failure of release causes sshguard to exit with non-zero value

[Trishank K. K. <tk...@ny...>]

Hello,

I have sshguard-1.4 installed on OS X 10.6.2 with the "tail log" and 
"ipfw" setup.

Every time I start sshguard, it would eventually exit in the near future.
I think the following output may point to the reason:

...
Dec 22 15:14:18 hostname sshguard[7993]: Releasing 121.52.215.180 after 
466 seconds.
Dec 22 15:15:27 hostname sshguard[7993]: Releasing 121.52.215.180 after 
535 seconds.
Dec 22 15:15:27 hostname sshguard[7993]: Release command failed. Exited: -1
...
Dec 26 13:21:21 hostname sshguard[27412]: Releasing 220.162.241.11 after 
441 seconds.
Dec 26 13:22:06 hostname sshguard[27412]: Releasing 220.162.241.11 after 
486 seconds.
Dec 26 13:22:06 hostname sshguard[27412]: Release command failed. Exited: -1
...

It appears to *sometimes* release, more than once, the same IP address.
Could someone tell us whether this is expected behaviour?
If not, then what is a solution?
Thanks for your time.
