[jira] [Comment Edited] (KAFKA-6194) Server crash while deleting
segments
[ https://issues.apache.org/jira/browse/KAFKA-6194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16246809#comment-16246809 ]

---------------------------------------------------------------
In 1.0/trunk, `deleteSeg` wraps the delete in `maybeHandleIOException`:
{code}
def deleteSeg() {
info("Deleting segment %d from log %s.".format(segment.baseOffset, name))
maybeHandleIOException(s"Error while deleting segments for $topicPartition in dir ${dir.getParent}") {
segment.delete()
}
}
{code}
This means that the log dir is marked as offline due to:
{code}
logDirFailureChannel.maybeAddOfflineLogDir(dir.getParent, msg, e)
{code}
was (Author: ijuma):
In 1.0/trunk, the exception is caught by the `deleteSeg` itself:
{code}
def deleteSeg() {
info("Deleting segment %d from log %s.".format(segment.baseOffset, name))
maybeHandleIOException(s"Error while deleting segments for $topicPartition in dir ${dir.getParent}") {
segment.delete()
}
}
{code}

> We upgraded our R+D cluster to 1.0 in the hope that it would fix the deadlock from 0.11.0.*. Sadly our cluster has the memory leak issues with 1.0 most likely from https://issues.apache.org/jira/browse/KAFKA-6185. We are running one server on a patched version of 1.0 with the pull request from that.
> However today we have had two different servers fall over for non-heap related reasons. The exceptions in the kafka log are :
