Hi Sean,
we use jackrabbit in the version 1.0.1 with the follow exclusions:
<dependency>
<groupId>org.apache.jackrabbit</groupId>
<artifactId>jackrabbit-index-filters</artifactId>
<version>1.0.1</version>
<exclusions>
<exclusion>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
</exclusion>
<exclusion>
<groupId>xerces</groupId>
<artifactId>xmlParserAPIs</artifactId>
</exclusion>
</exclusions>
</dependency>
Do you restart your server to solve this problem,or only the
jetty/tomcat engine(Web-server) on it? We have to restart the server
machine (server tower) complete before exporting!!!When I only restart
my jetty engine I get a heap space error again. But we have a live
server,many projects run on it,therefore it's very unprofitable to shut
and restart the server. All websites are not reachable for that time.
Fryday I try jackrabbit in the version 1.3.1 (magnolia 3.0.2).Maybe with
success. But I don't think so...
It looks like a memory leak of some kind,your right...
By the way,what do you thing how many heap space should be enough for a
75MB large section of a website....800MB are to much,I think??
Anyway I will report my next experiences with that problem....
Thanks for your fast answer...

Hi Anja,
I don't have any advice for you, though I can confirm that we see similar
behavior. We've started bouncing our server right before doing backups to
help with this behavior, which looks a lot like a memory leak of some kind.
Out of curiosity, which persistence manager are you using? We've been using
BDB (the non-magnolia version) so far, but are hoping to switch over to
Jackrabbit 1.3.1/JNDIPooledDatabasePersistenceManager/Postgres soon, as
we've seen an increasing number of issues with the data store and hope that
the more robust PM will help with all of that.

Hi,thanks for your answer.
Yes I have already try to export section of my website individually. The
error page is already located (one 75MB large section). All sections of
my website except this one (film section/node) works.
But something I don't understand :
I export this section separately.My java heap space I have placed to
800MB (maxmemory=800MB),beacause under this max.limit the export never
works. (my section is 75MB large..very large....).Sometimes it works,but
often I get the heap space error again. After a complete restart of my
server (pc on which the server run) the export of the 75MB large section
works. If I only restart the jetty engine the export will fail! (heap
pce error)
But after a few ours ( I did a lot of other things on the server and
with magnolia) I tried the exporting again and it failed again. If I
restart my server,it works with 800MB heap space...I can export the
section five,six times....but at any time I get the heap space error
again or when I do other things in between.
Ours later or Minutes later the same problem.
It seems that the automatic release of store doesn't work accurately.I
have no idea when the garbage collector gives store free. But at any
time my heap store is full and I get the heap space error. A restart of
my server to make an export possible should not be a solution. (LIVE
Server).
Have any of you an advice for me...a hint or something like that.
I have no idea.
