“There is a number of web hosting situations where PHP
applications appear to misbehave during large upload operations.
This may happen, for example, when dealing with attachments via
webmail clients like roundcube or during the upload of files to
document management applications.“Things get more difficult if we are talking about shared
hosting on an apache + mod_fcgid + php environment, as there are
several different parameters to be tuned in order for large uploads
to work.“As far as we could see, there’s a lot of people hitting
different limits in their applications and looking for solutions,
but no handy summary of where to make the necessary changes.”
