RSSL buffer failed

clapun

Has anyone come across this error ? It appears every time when traffic volume is high, RFA got disconnected and got this error. Any hint to indicate what might be the issue ?

INFO (FA_LOG) Publisher 0: OMM error event received: Attempt to get rssl buffer failed! Please check log for details. Client session could have already disconnected.

When publishing a message, the message is written to the internal
buffer before sending it to the network. This buffer is reserved when the
channel is created and its size can be configured by using the following RFA
configurations for RSSL_PROV connection type.

• bufferPoolSize
  Sets the maximum size of the buffer pool, which is
  shared among all server-side RSSL channels. Each RSSL Server can have its own
  buffer pool

• guaranteedOutputBuffers
  Number of output buffers that are guaranteed to an
  RSSL channel. Once this value is reached, the channel will start using pool
  buffers, if available. Guaranteed output buffers are allocated on a per channel
  basis

• maxOutputBuffers
  Maximum number of output buffers allowed to an RSSL
  channel on the server side. This is the number of guaranteed output buffers
  plus the number of pool buffers available to this channel
  
  Once this value is reached, the channel will be
  unable to get any new buffers until some of the currently held buffers are
  released

This error “Attempt to get rssl buffer failed!”
indicates there are no buffers available to the API. This typically occurs
because:

• The channel has been disconnected

• The network issue

• The client application is a slow consumer

"Attempt to get rss buffer failed!".

I wonder what "rss" is or if that is just a spelling error ? Btw: You haven't specified which of the RFA APIs you are using (C++, Java, .NET).

sorry typo should be rssl buffer. API is using C++

Hi,

@clapun

There was a bug in RFA C++ 7.2 that was fixed in RFA C++ 7.4.0.L1 as described below:

rfasl10803;Provider may not get InactiveClientSession event when consumer is killed The provider application may not able to get InactiveClientSession event when the consumer application is killed. If the application still publishes data to inactive client, a lot of the error message "Attempt to get rssl buffer failed! Please check log for details. Client session could have already disconnected" are generated in rfa log file.

Can you confirm which version of RFA C++ you are using?
