Yes, I have updated tried both. I stated that in my other post. Maybe you might have not seen it.
Also, to be clear, I didn’t think there was a way to disable backpressure. You can only extend the backpressure check time, which is what I did.

Have you tried disabling the backpressure mechanism and limiting the in flight messages with topology.max.spout.pending ? https://storm.apache.org/releases/current/Performance.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__storm.apache.org_releases_current_Performance.html&d=DwMFaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=BxRQQZWnE3D8_17HHQE0-XVUNXeS_tqliMsO6ITEvoM&m=s47ZhwnlsJfgRfqqRdG5OTTKWEhdHkgLkGtF_SjROaMshzIe6FWZkzm5zgkrjsUm&s=LZzB9UAuLr_8bW2hG700FHwj68JSQHEtSCVG4Rd4lis&e=> On Wed, 20 Apr 2022 at 17:04, Le, Binh T. <binh.t...@accenture.com<mailto:binh.t...@accenture.com>> wrote: Hi Bipin, Thanks for your response. Unfortunately, this problem is not easily reproducible. It only manifests itself when we're running our topologies with production volume. It works fine, so far, with low volume. So it would be difficult for me to provide an example topology and all that, to reproduce this. Before storm 2.4.0 was released. We did try upgrading to 2.3.0, but unfortunately encountered tons of errors we've not seen before with 2.2.0. So we reverted back to 2.2.0. At this point, I'm not sure if we can upgrade to 2.4.0. We'll see.

Hello Binh, Can you can provide a small example that can be duplicated - for example with a storm config file (storm.yaml) and default, and running WordCountTopology (for instance). Please check the CLASSPATH and java version, and any Exception in the log files as well (before the NPE). For debugging locally, you can set_log_level for a specific class for a specified duration (using storm.py), and/or start in java debug mode and attach a debugger to it. From your earlier description of the stack trace, it seems there is a storm internal error when the message is retrieved from the queue. Is it possible for you to switch to the latest released version of storm (2.4.0). You might get better support for it. If the problem still persists, please raise a storm-jira at https://urldefense.proofpoint.com/v2/url?u=https-3A__issues.apache.org_jira_projects_STORM_issues&d=DwIFaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=BxRQQZWnE3D8_17HHQE0-XVUNXeS_tqliMsO6ITEvoM&m=HLhVczPJ4MPWrYsR8Lap37z-NJEPIiIKCwq_thIXP-rlAYKZZpv1VjC7H4Of-1HC&s=5ZSfHRDiQM7q6Z22OTpYVihJx1X1508wu1RadoWQ72k&e= Thanks --Bipin On 2022/04/18 17:17:04 "Le, Binh T." wrote: > Hi, > > We are upgrading our Storm 1 cluster to 2.2.0 and noticed a strange behavior. > The topology is processing millions of messages fine.
