Hi,
Even changing pools setting like
Increasing the pool size resolved the problem, specifically the
following parameters (neatly copied from the tomcat users guide)
<Parameter
name="max_threads"
value="200"/>
<Parameter
name="max_spare_threads"
value="20"/>
<Parameter
name="min_spare_threads"
value="20" />
The values were arbitrary - I stuck mine up to max_threads = 200,
max_spare_threads=20, min_spare_threads=20
and lo - the hang problem went away.
Even I had used options
TOMCAT_OPTS=" -Xms64m"
Didn't solve the problem.
Still same problem.
Regards,
Santosh Pasi
