Patch originally by Alfred Kayser, updated by Josh Aas, final fix from Michal Novotny. r=michal

We should probably just back my patch out unless we can find a fix very quickly.

It seems to be fixed with STR in Nightly20.a2(hourly build) by back out Bug 405407. http://hg.mozilla.org/mozilla-central/rev/a9d59073400b Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20.0 Firefox/20.0 ID:20121120065452 However, "XML Parsing Error: unexpected parser state" happens at the first load(Step5,6) sometimes and should be Bug 569229 .

bug 405407 is being backed out of Aurora/Beta, no need to track this specifically.

To be retested with 814010.

This should be resolved with the backout of 405407.

Alice, could you confirm this is also fixed in Firefox 18 beta2 and F19? I can't reproduce this on Windows 7.

I cannot reproduce the problem with STR comment#0 in 18beta and Aurora19.0a2 any more. http://hg.mozilla.org/releases/mozilla-beta/rev/6eb5edeb9f52 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0 ID:20121128060531 http://hg.mozilla.org/releases/mozilla-aurora/rev/c1e60736791c Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/20121203 Firefox/19.0 ID:20121203042014 And sometimes as same as Nightly20.0a1, "XML Parsing Error: unexpected parser state" happens at the first load(Step5,6).

Thank you! I'll mark this as verified.

I just ran into this in a Feb-25 Nightly: XML Parsing Error: unexpected parser state Location: jar:file:///C:/Program%20Files%20(x86)/Nightly/omni.ja!/chrome/toolkit/content/global/netError.xhtml Line Number 311, Column 58: <div id="ed_netInterrupt">&netInterrupt.longDesc;</div> ---------------------------------------------------------^ I don't have good STR, but there's still an underlying intermittent issue :/

This bug is fixed per backing out old patches from bug #405407 You're talking about bug #569229

In Bug 725993 there is a comment that possibly antivirus scanner may be involved: "I wonder if users are seeing these freezes caused by this due to disk activity on their systems by virus scanners (some people even run multiple scanners!) or the OS's search indexing service (SearchIndexer.exe) misbehaving.". In almost all of the diskcache write crashes there is a thread with: 4 xul.dll nsDownloadScannerWatchdog::WatchdogThread toolkit/components/downloads/nsDownloadScanner.cpp:669

Also netError.xhtml is not loaded through the diskcache (or cache at all), so I am wondering how this netError.xhtml can be related to the diskCache?

Dup of Bug 569229 ???

I have not seen this in a loooong while. So we can probably call this fixed.
