[BUG] Network crashes after a while

[Aran30]

1. Summary - After letting a network run for a while, it will crash with some "Thread-pool-..." error. To make it work again, the whole network needs to be restarted. Services are unusable during that time.
2. Bug Details
   1. What? - Weird error occurs after a while, making bootstrap node not work anymore.
   2. Where? - In our main network on kubernetes.
   3. When?/How often? - Maybe after 4/5 days.
   4. How?/Current state - A possible for this to occur, is that maybe some threads in las2peer are not closed correctly, leading to an overflow of threads. Another guess would be that some services make too many requests, which leads to las2peer not being to create new threads for the barrage of requests.
