[ http://issues.apache.org/jira/browse/FORTRESS-22?page=comments#action_12460251 ] Jörg Heinicke commented on FORTRESS-22: ---------------------------------------
Should be moved from Fortress to Excalibur Components (EXLBR), probably best with a new component "Sourceresolver". > ResourceSource.getInfos() leaves URLConnection open, resulting in 'too may > open files' condition > ------------------------------------------------------------------------------------------------ > > Key: FORTRESS-22 > URL: http://issues.apache.org/jira/browse/FORTRESS-22 > Project: Excalibur Fortress > Issue Type: Bug > Components: Implementation > Affects Versions: 1.0 > Environment: Sun Solaris 5.9 > JDK 1.4 > Cocoon 2.1.8 > Reporter: Ellis Pritchard > > org.apache.excalibur.source.impl.ResourceSource#getInfos() opens a > URLConnection [line 79] to obtain information about the resource, however, it > does not cause this connection to be closed (i.e. call getInputStream() and > then close() that), thus the resulting file-descriptor will only be closed > when the garbage collector collects the URLConnection object. > Quote from java.net.URLConnection javadoc: > "Calling the close() methods on the InputStream or OutputStream of an > URLConnection after a request may free network resources associated with this > instance, unless particular protocol specifications specify different > behaviours for it." > On a high-load system, which is accessing resources in jars frequently (even > if only as a side-effect of calling getValidity()), this may result in all > available file-descriptors being used within a short period, and because GC > is not kicked off when a process runs out of file-descriptors, this can > result in a DoS. > This problem has occured on a live system running Apache Cocoon 2.1.8. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
