[jira] Commented: (WICKET-2075) Pagemap is locked forever with some
Page serialization exceptions
Posted by "Alex (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/WICKET-2075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12671881#action_12671881 ]
Alex commented on WICKET-2075:
------------------------------
The cause of the serialization issue was the described in JIRA 2077. However it looks like that runtime exceptions thrown from within AbstractPageStore.serializePage are not handled correctly and leave the page map(s) in the locked state. After that happens some/all other pages in the application can not be accesses at all (waiting on the lock). The call stack where this effect was happening is below.
As I said the original problem was the "NoSuchMethodException" in the SerializerChecker, but I think the same problem would happen with some other exceptions as well. The "unlock" code should be hardened against such problems.

[jira] Commented: (WICKET-2075) Pagemap is locked forever with some

Martin Makundi commented on WICKET-2075:
----------------------------------------
Hi!
I still get pagemap locked "forever" and kill -3 shows nothing is happening.
Is there more insight to this issue? Users can login again if I ask them to restart browser.
I have also made sure that it cannot be a database lockstate, I added similar watchdog timer to database threads and it says there is no ongoing database activity during pagemap infinite lock.
