you mean, is it problem with comm.jar library? or the serial gsm
modem that I am using?
I am using two modems with same model,I never tried a diiferent model.
And I tried "-Dsmslib.serial.polling" and other parameters like "-
Dsmslib.serial.pollinginterval","-Dsmslib.serial.keepalive=nnn","-
Dsmsib.watchdog=nnn" .It does't work still one modem is using 50% CPU.
I have to tweak these parameters and check the performance on linux.
As I already have the SMSLib project setup , I also tried
changing the SMSServer.conf smsserver.balancer to below one and
rebuild the jar.There is no improvement in performance.
# Set a different balancer than the default.
smsserver.balancer=LoadBalancer
Any suggestions to fix this problem really helpful.
Thank you,
Ravindra.
Please
