CSV redirect upload-limit

Hi,

I have a large number of redirects (almost 2000) and when trying to upload these as a .csv only a part of them get uploaded;

– The first time I uploaded the whole file around 860 of the 1935 redirects were uploaded

– The second time I uploaded the file without those 860 redirects (so with 1075). This time only around 400 were added to the list in the system.

My question is now: is there an store- or uploadlimit set for the redirects (and can this be changed?) or is this the plugin hitting the php memory limit and then quitting?

Thanks in advance!
