I know there have been quite a few posts about nph-build but I think I've read them all and I can't find a solution to my problem. I've used the script for a month and have 1200 links, now all of a sudden build/staggered/auto freeze in the middle of the building process. Many people have posted the solution of using telnet or making each category less than 50 links to stop the process timing out. I'm not able to use telnet and I've reduced the galleries to having no more than 40 links each and it still freezes. At first I reduced the category size by spreading the links over multiple versions of the same category so the 160 links in CAT became CAT (40 links) , CAT2 (40 links) etc. But when I ran build it would come up with the unknown category error for the CAT2 category. Now I've moved the extra links into sub categories of the first so I have CAT/ (40 links) , CAT/2/ (40 links) etc and it still freezes when it tries to run the sub categories. If anyone has any ideas I would greatly appreciate it as I'm stuck.
