Out of memory when building PHP project [message #58970]

Thu, 18 October 2007 05:44

Eclipse User

Hi All,

Every time I open a PHP project (around 50 PHP files total) I get out
of memory error and occasionaly eclipse freezes for a time while
'building' the PHP project.

Anyway, I tried increasing all VM parameters as much as jvm would
allow me (on a 2GB machine), eclipse.ini looks like this:

-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-XX:MaxPermSize=256m
-Xms512m
-Xmx512m

But I still keep getting this:

!ENTRY org.eclipse.core.jobs 4 2 2007-10-18 11:42:06.984

Oh... and code completion doesn't work after the error.

Hi Bogdan,

This is a frequent and serious problem for me also. I've raised a bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=206109

I am surprised you get it on a project with so few files, but I think it
is just a memory leak somewhere, maybe something in one of your files is
triggering it. I did notice a php file in the YUI library with a 1.5mb
string which can single handedly kill PDT for me.

You can sort of work around it by turning off 'Build Automatically' from
the Project menu... but as you mentioned, if a project fails to build
then code completion, find declaration, outlines, and most of the other
stuff that make an IDE useful stop working.

Go add your vote!

Cheers
Tom

Also, your stack trace looks a little different to mine, you should post
that to the ticket also.

I think the build process is particularly flaky and can break in several
ways.

This bug sounds familier. It might be the same as
https://bugs.eclipse.org/bugs/show_bug.cgi?id=203984 which was fixed in
the last integration build. You should try the I20071001 build and see
if the problem still occurs.

Regards,

Marijn.

You are setting MaxPermSize twice there - probably not a problem but
anyway.

I've got a 2GB machine too, and my eclipse.ini looks like:
-showsplash
org.eclipse.platform
-vmargs
-Xms256m
-Xmx1024m
-XX:MaxPermSize=256m

which seems to have gotten rid of out-of-memories. What could be
happening is that your MaxPermSize is too close to -Xmx, so that the
heap runs out of memory.

How about either
- increasing -Xmx to 1024
- reducing MaxPermSize to 128m (which I believe should be well enough
for perm)

..k

Hi Tom,

I tried lots of hacks, finaly deleted /.cache/model.dat (or something
like that, don't remember anymore) and after restarting eclipse all
worked. Though it might have been anything else I tried before that :)

Hi Bogdan,

that worked for me too, thanks a million for that hint!! :)
The file was named /.cache/.dataModel btw.

Solution (helpful for me):
1.step
identify trouble project in workspace
start eclipse (ignore errors ... no close)
Close all projects
shut down eclipse
start eclipse
Open each projects (one after another)
on error stop (it is THE BAD PROJECT)
Close 'THE BAD PROJECT'
Delete 'THE BAD PROJECT' !!!!! DO NOT DELETE CONTENT !!!!!
shut down eclipse

2.step
increase memory limits
For 2Gb Ram is good idea something like:

-showsplash
org.eclipse.platform
-vmargs
-Xms256m
-Xmx1024m
-XX:MaxPermSize=256m

3.step
delete from project folder these files (all project setting !!!):
cache
project
settings

4.step
start eclipse

5.step
import THE BAD --GOOD FOR NOW-- PROJECT as PHP Project

?
