I suppose one of two (or both) of the following things might be kicking 
in;

- PHP runs out of time (by default, the execution time limit for PHP 
is, IIRC, 30 seconds),

- PHP runs out of memory (not sure what the default du jour is).

Both of those issues should log to Apache's error log though, or 
/var/log/roundcubemail/errors for the PHP error log is redirected.

I myself have no issues with folders with hundreds of thousands of 
messages - albeit searching might be a little slower, and the thread 
view obviously takes a little more time.

That said, the thread view - if large chunks of the 100s of Ks of 
messages are in fact in threads - using a default page size of 40, lists 
all messages in the first 40 *threads* - this can amount to hundreds of 
messages - each of which need to be fetched the headers for.

I myself run with imap and message caching enabled, ensuring that any 
such caching will only need to be initialized once - which is also when 
opening such a folder takes the longest time. Revisiting the folder is 
definitely significantly faster for me afterwards.

Kind regards,
