gem management requires too much memory
---------------------------------------
Key: JRUBY-2684
URL: http://jira.codehaus.org/browse/JRUBY-2684
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.1.2
Environment: Linux satumaa 2.6.24-19-generic #1 SMP Wed Jun 4 15:10:52
UTC 2008 x86_64 GNU/Linux
Reporter: Erno Mononen
Assignee: Thomas E Enebo
Gem management (listing remote gems, installing new ones) seems to require huge
amounts of memory on my configuration. Without increasing Xmx I get OOEM
everytime with the following command:
[EMAIL PROTECTED]:~$ jruby -S gem list --remote
*** REMOTE GEMS ***
Bulk updating Gem source index for: http://gems.rubyforge.org/
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit
exceeded
at java.util.TreeMap$Values.iterator(TreeMap.java:932)
at org.jvyamlb.ScannerImpl.nextPossibleSimpleKey(ScannerImpl.java:857)
at org.jvyamlb.ScannerImpl.needMoreTokens(ScannerImpl.java:472)
at org.jvyamlb.ScannerImpl.peekToken(ScannerImpl.java:422)
...
Also with 600m:
[EMAIL PROTECTED]:~$ jruby -J-Xmx600m -S gem list --remote
*** REMOTE GEMS ***
Bulk updating Gem source index for: http://gems.rubyforge.org/
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at org.jruby.util.ByteList.grow(ByteList.java:635)
...
If I set the Xmx param to > 1G then the command succeeds.
Tried with JDK 6:
java version "1.6.0_10-beta"
Java(TM) SE Runtime Environment (build 1.6.0_10-beta-b14)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b11, mixed mode)
And JDK 5:
java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_15-b04, mixed mode)
And got OOEM on both.
