Can't attach file bigger than ~6 MB.

[konstanta]

Hi guys.
Faced with strange issue on OTRS 3.2.1 and 3.2.5.
Trying to attach file to Email ticket bigger than ~6MB got an error. Depends on filesize, Chrome throws me error :
1.

Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

- for files 7-8 MB in size. Uploading indicator came to 100% and straight away Chrome throws me this error.
2.

Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.

- for files bigger than 9 MB. Uploading just stops in the middle and Chrome throws this error.

Apache access log shows me this string in that moment:

Code: Select all

xxx.xxx.xxx:80 xx.xx.xx.xx - - [23/Apr/2013:12:11:26 +0000] "-" 408 0 "-" "-"

All other logs are empty.

Max_allowed_packet and WebMaxFileUpload both have appropriate values:

Code: Select all

mysql> show variables like '%max_allowed_packet%';
+--------------------+----------+
| Variable_name      | Value    |
+--------------------+----------+
| max_allowed_packet | 52428800 |
+--------------------+----------+

/opt/otrs# egrep 'WebMaxFileUpload' Kernel/Config/Files/*
Kernel/Config/Files/ZZZAAuto.pm:$Self->{'WebMaxFileUpload'} =  '16777216';

I also tried to change that values, got exactly the same behaviour. Tried to change 'WebUploadCacheModule' -> FS , got same errors.

Installed fresh OTRS 3.2.5 with empty database, but took Kernel/Config.pm, Kernel/Config/GenericAgent.pm, Kernel/Config/Files/ZZZAuto.pm from my production system and still I can upload attachments only up to 6 MB in size. So those config files are problematic maybe?

BTW , bin/otrs.CheckModules.pl tells me that everything is ok (except of some optional modules). I can successfully upload file less then 6 MB and I see it in MySQL after uploading...

Someone can give me a direction, where to search for a bug or missconfiguration?

And sorry for my English

if you're using database file storage, the limit is in the database. Check the mysql ini (my.ini?) file for limits.
