Hi Oscar,

It sounds like your app is deadlocking hanging waiting for a timeout.  This can make wotaskd think that it is dead.  When this happens, try doing this

sudo jstack –F <process id of application instance>

And post the results to the list.

Hi list,
I have a problem staring my application from monitor it appear dead.
The process is alive in the system I have to kill it to be able try again.
I don't know what is this issue.

webobjects 5.3.3
ubuntu linux 12.04
apache 2.2
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

sudo lsof -P -i tcp:1085 
COMMAND  PID      USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    1720 appserver  116u  IPv4  42087      0t0  TCP *:1085 (LISTEN)


The wotaskd log throw this.
2014-03-20 17:47:03,154 WARN  79.76 MB/72.24 MB [main] logging.ERXNSLogLog4jBridge (ERXNSLogLog4jBridge.java:44) - Application 'logistica-1' on localhost:2002 stopped running at 2014-03-20 23:47:03 Etc/GMT.
The app's current state was: STARTING.
The app did not respond for 63521279103seconds which is greater than the allowed threshold of 120000 seconds (Lifebeat Interval * WOAssumeApplicationIsDeadMultiplier) so it is assumed to be dead.
The last successful communication occurred at: 1-04-25 00:00:00 Etc/GMT. This may be the result of a crash or an intentional shutdown from outside of wotaskd
 
Thanks in advance.
