[Wrapper-user] Newbie (?) Questions

[Georg S. <geo...@ti...>]

Leif,

a few hours ago I downloaded the Wrapper 3.0.4 in order to improve the 
uptime of my JBoss servers. Everything works fine so far, but now I am 
not sure anymore, whether Wrapper can solve my problems.

1) Restarting after OutOfMemory exceptions works after defining the 
appropriate filter. I also want the wrapper to restart the server at 
most 5 times. When I tested this by specifying 8 MB max. heap, the 
server was restarted continuously (had to kill it after jvm 7 came up).

2) The second problem is, that the (locally running, nohup-started) 
servers go down, when the network goes down. They seem to get a "normal" 
TERM, just like pressing Ctrl-C or issuing a kill (without -9). JBoss 
shuts down cleanly, working its shutdown hook, but Wrapper does not 
restart the process, as I expected. I introduced a filter, that checks 
for "Shutting down the JVM" string and then triggers a RESTART. The 
filter matches, but no restart occurs, instead the wrapper stops.

3) I could not find a parameter to control the ping frequency (not the 
timeout). The ping slows down the application, and for a server, that 
should be running for half a year a ping every 30 seconds or similar 
would be good enough.

I attach the configuration file I use. It should be ok, though, at least 
I don't see any error messages during startup.

Am I missing something?

Regards
Georg
