Memory grows and grows

Post by ace16vitamine » Tue Jul 10, 2018 6:59 am

Hi,

I have a small script and I have no Idea what is going on wrong. After 24h the application is frozen, I monitored the task manager and identified that the memory usage is growing and growing.

The script is something like a HUB. It received datas from other Applications (over socket) every minute and deploy this informations to mobile client applications (also with socket). But every minute the mem usage is growing for 200-800k...

Example, every minute a server is contacting the hub and transfer informations:
accept connections on port 9999 with message "verbindung_client_read"
...
...
get the informations from server...
write it to sqlite DB
...
---
write the informations to mobile client
1) My first Idea was that there is a growing Variable. I startet to clean up all Variables every time but it does not help.

2) I checked every loop, case etc , but the script is clean

3) DBCons are open, closed etc. No issue here. Same with Sockets. After the communication the socket is closed.

Any Ideas how to clean up the memory?

Thanks
Stefan

How did you check the number of open sockets?

And do you use any timers?

I am not using timers (this was also my first Idea).

To check the open sockets I am using

the opensockets (..) in the message box, but all sockets are closes successful. What I find out: I have the same issue if a client connects to collect datas, the socket can be the problem.

Every time the Client or Server is opening a connection to the hub the RAM usage is growing on the HUB

This seems rather high. I would post the stack to QCC.

I can confirm that it is not growing with LC 9.0.1 RC1 Win. I can see some smaller thinks but thats normal, for me it looks like stable now.

Thank you for your help.

Stefan
