Subject [jira] [Commented] (CASSANDRA-3991) Investigate importance of jsvc in debian packages
Date Thu, 15 Aug 2013 16:38:49 GMT


Eric Evans commented on CASSANDRA-3991:

The issue I described originally can be repro'd 100% of the time. I've seen this burning people
on irc who install from the debian package (thus getting jsvc) and wanting to use a tiny jvm
for development.

After all this time, I'm not sure I tested that.  If it struck me then the way it does now,
I might put it off.  Certainly, {{jsvc}} can't be the only obstacle to running under such
low memory requirements.

I _have_ spent a fair amount of time trying to reproduced the runaway utilization and memory
leak complaints, to no avail.

> jsvc seems to be buggy at best.  For instance, if you set a small heap like 128M it seems
to completely ignore this and use as much memory as it wants.  I don't know what this is buying
us over launching /usr/bin/cassandra directly like the redhat scripts do, but I've seen multiple
complaints about its memory usage.
