[imp] ActiveSync not syncing for one user

[poubeline at free.fr]

Hi All, 

I have made some new search on the web for this issue and I have found this article: 
http://horde.690.n7.nabble.com/Tickets-14550-Active-sync-via-outlook-resulting-in-memory-exhausted-td139027.html 

In this article I have found the following info: 
"Trying to fix this in the PEAR Math_BigInteger library is becoming a 
huge undertaking. For now, try installing either the bcmath or the gmp 
php extension. I've tested both locally and either one will prevent 
this issue. " 

I have installed both bcmath and gmp for PHP7.0 on my Debian Stretch. 

Do you think I need something else ? 

I can test this solution only tonight so if you have thoughts about it, they are welcome. 

Thanks

Objet: [imp] ActiveSync not syncing for one user 

Hi all, 

I have 2 users that are currently using the Horde ActiveSync feature and since the upgrade to the latest ActiveSync version, I got the following error for one user in syslog file : 

HORDE: Allowed memory size of 134217728 bytes exhausted (tried to allocate 150994944 bytes) [pid 29577 on line 1090 of "/usr/share/php/Math/BigInteger.php"] 

I have seen a recent log from Luis F e lip e Ma r zaga o about this kind of error but for /us r /s h a r e /p h p/ H o r d e /St r e am.p h p and he found that the user had more than 13k messages in the trash folder. 
I have reviewed the user messages and there are 2 808 files for a total amount of 659,6 Mo. 

I am running the following : 
Horde 5.2.16 
Imp 6.2.20 
Horde Groupware Webmail Edition 5.2.21 
Horde_ActiveSync 2.38.8 

I tried to activate the logging using the /var/log/horde_mobile_access.log file but I cannot get this file to be created. 

Anyway, can anyone help me with issue as I don't have a clue on what's going one for this user ? 

Thank you
