Hi all,
We are working on:
s7g2 (Custom Board)
SSP 1.7.0
e2Studio 7.8.0
API: Netx Duo.
The activities in IP Stack:
1. WebServer, (User Login)
2. TCP/IP Server (Periodical)
3. imcp (ping test for gateway link) (Periodical)
In few cases we find that the IP Tasks (mentioned above) stop working completely.
No Response to ping,
Webserver Login page does not load,
TCP/IP Server does not respond.
However other non-IP related tasks such as OLED etc are still running (Not a crash)
Any idea what can cause this?
There is no timeline as to when it occurs, 1hr, 1 day, 1 week...
I went through a lot of related threads.
One of which is very similar to my condition:
https://community.renesas.com/embedded-system-platform/synergy/f/forum/17295/ip-instance-stops-working-ssp-1-7-12
Is it because of High Traffic Network.
I hope Renesas Team can shed some light on it.
Regards,
Surojit
Hi Surojit,
How are things going? Were you able to find a workaround for this issue? Have you also tried the suggestions mentioned by Larry and Sekar in this thread: https://community.renesas.com/embedded-system-platform/synergy/f/forum/18061/web-server-stops-working-after-some-time?

Hi JB,
The link you mentioned about Sekar and Larry, We have already tested the same, but my question is why cant the device work without a switch.

Hi All,
I have been able to recreate the problem of IP freeze,
When I use
https://www.veeam.com/agent-for-windows-community-edition.html
for backup on the same network, The IP stops responding completely during this backup duration. I find that the MODBUS Slave Task looses Packet Pools (Transmit has a dedicated Pool)
This has become a grave concern, this does indicate Network Traffic Congestion is causing the problem,
If I am right then what is the solution....
Please Help!!!
Does anybody have a lead on this?
Please share if so.
Hi All, I am sharing a screen shot of the primary IP Pool which after Network Congestion during test shows only 12 packet pools are available although the pool size is 50. Each time we Test the available packet pools decrease substantially. I have a few questions: 1. Why are the pools not becoming available? 2, What will happen if packet pool available becomes 0 and how do we make sure this never happens? 3. How do I find out which task/service is still occupying the pool?
Hi,is there any solution for this problem? We have exact the same behaviour of the ip framework. After some time there is no response to any messages.. We are working with SSP version 2.0.0
We have not found any solution till date.
Hi Josh,
Were you able to find the solution yet,
Pool Depletion happens every now and then and finally the IP stops working.
NetX should release the packet when it's fully transmitted - the send case. On receipt, you release it when it fully processed. I think the applications that process the packets should free it automatically when processed - eg a packet processed by the web server. If you are processing packets directly, you have to free.
Are you sending packets to somewhere where the connection is dead - may the packets there are being consumed and not released?
