Error 500: Internal Server Error - After !!202!! search

[Percent01]

I use Recoll 1.19.14 with XapianDB 1.2.17

I start webui this command: "nohup python ./webui-standalone.py >/dev/null 2>&1&"

I get this error message after !!202!! searching (I test many times and I always get error message after 202. webui search):

Sorry, the requested URL 'http://X.X.X.X/results?query=asdf&dir=%3Call%3E&after=&before=&sort=relevancyrating&ascending=0&page=1' caused an error:

Internal Server Error

Exception:

EnvironmentError("Can't open index",)

Traceback:

I got this message on the console:

I got this comment from XapianDB guys:

"The issue is what it says - there are too many open files. We need some free file descriptors to open the index, but there are a finite number available - e.g. on modern Linux the limit is 65536. So it sounds like recoll isn't closing files in some case, as it's unlikely it really needs so many files open at once.

This is a recoll issue, not a Xapian one. There's nothing we can really do if there aren't file handles available, short of randomly closing some which wouldn't be helpful overall."

This is quite certainly a problem in the Recoll Python module. No need to bother Xapian or Webui for now :) Working on it.

It was fixed in Recoll 1.19.14p1 version.
