The eclipse plugin doesn't use or redeploy using the hot deploy

you some your are creating the eclipse projects inside the hot
deploy directory or doing something to write out to it that is
trigger some weird behavior.
The fact that other eclipse plugins (MyEclipse) is seeing a
similar problem is strange and indicates to me a problem on the
server side, but unless i have a test case that shows the behavior
this is difficult to debug.
Sachin's hot-deploy theory seems reasonable to me (having a hard
time explaining the behavior, otherwise). If true, sounds like
there are potentially two problems: 1) hot deploy causing multiple
deployments and 2) a ClassLoader memory leak.
Regarding 1), the default polling interval for the hot-deployer
gbean is 2 seconds. Increasing this polling interval may help.
Locate the hot-deployer module in var/config/config.xml And replace
with something like (untested):
<module name="geronimo/hot-deployer/1.1.1/car">
<gbean name="HotDeployer">
<attribute name="pollIntervalMillis">20000</attribute>
</gbean>
</module>
BTW, a 20 second poll interval may be a bit extreme. IIUC, it may
cause up to a 40 second delay in the hot-deployment of your
application. You might prefer a more modest increase...

Regarding 2), I ran deploy/undeploy (redeploy) tests on 1.1.1 using
Daytrader. I didn't see any ClassLoader memory leaks, in these
tests. However, I didn't test using hot-deploy... Seems like
several possibilities:
1) There's a general deploy classloader memory leak in Geronimo
which we didn't find,
2) There's a hot-deploy-related classloader memory leak in Geronimo,
3) There's a bug in your application(s) causing a classloader
memory leak.
If you have a sample application which shows the problem, I'll have
a look...
