[imp] Endless loop after imp upgrade 5.0.13 to 5.0.14

[Martin Baum]

Hi,

after upgrading from imp-5.0.13 to imp-5.0.14 on a busy site I am  
seeing php-processes that get stuck in an endless loop until PHP  
max_execution_time is reached. Does anybody see the same behaviour?

max_execution_time is reached in different parts of Tree.php so I am  
unable to locate the cause for this. Here goes my log:


[20-Oct-2011 11:57:16] PHP Fatal error:  Maximum execution time of 300  
seconds exceeded in /path/imp/lib/Imap/Tree.php on line 1709
[20-Oct-2011 12:30:08] PHP Fatal error:  Maximum execution time of 300  
seconds exceeded in /path/imp/lib/Imap/Tree.php on line 1279
[20-Oct-2011 12:31:31] PHP Fatal error:  Maximum execution time of 300  
seconds exceeded in /path/imp/lib/Imap/Tree.php on line 829
[20-Oct-2011 12:37:44] PHP Fatal error:  Maximum execution time of 300  
seconds exceeded in /path/imp/lib/Imap/Tree.php on line 1722
[20-Oct-2011 13:00:56] PHP Fatal error:  Maximum execution time of 300  
seconds exceeded in /path/imp/lib/Imap/Tree.php on line 1277

I only see this with live traffic and unfortunately I can not  
reproduce it. strace / ltrace for php-processes shows nothing so the  
loop does not call any syscalls oder libcalls.

best regards,
Martin
