Wordpress BackupBuddy and LiteSpeed

[mistwang]

It is recommended to update 4.2.1 installation to the latest build, either force reinstall from web console, or from command line, do

/usr/local/lsws/admin/misc/lsup.sh -f -v 4.2.1

With the latest build, you may need to explicitly set "Auto Start" to "Through CGI daemon" for lsphp5 external app to make BackupBuddy work properly.

Hi,
After more testing, transfers are still not working reliably. Seems to work maybe once out of every ten attempts.

I have updated to v4.2.1 and changed the Auto Start option to "Through CGI daemon" and that hasn't helped.

It might be a problem on the server I am using at VPS.net, but when I switch back to Apache, transfers work fine, which points to a LiteSpeed issue.

FTP transfers with BackupBuddy seemed to be more reliable, but transfers to Amazon S3 or Rackspace Files... are always unreliable.

Do you have any other suggestions that I could try?

Thanks,
Kirk.

I think should strace the lsphp5 doing the backup to find out exactly what happened.

strace -tt -T -p <pid_of_lsphp5_doing_backup>

whether it is killed by LSWS, or due to PHP internal limit.

Ok thanks. I'll try and diagnose the issue and let you know what I find.

This isn't feasible under a shared environment as it will stop user php.ini's being called.

Does anyone have any more information on this problem?

We're still trying to find the root cause.

I've ran a strace on the process:

I don't see version 4.2.2 as option to upgrade (only up to 4.2.1 which we are currently running).

[webizen]

4.2.2 is released (beta) but not yet enabled in autoupdate. you can upgrade from command line as follows:

/usr/local/lsws/admin/misc/lsup.sh -v 4.2.2
