Search slowing down over time

[serzak51]

I have around 15 accounts that i use. The search works fine on the firsts accounts, but after a while the time between searches double after each searching, in the end making it wait ~15 minutes, and probably more if i let it run. Once the script is restarted, it goes on normally. I'm not really sure what is causing this, i checked the search part of the code and everything seems fine.
