Introduction 

An issue has been identified regarding the transfer of WA-*.log files from $IS_LOCAL/webadapter/log to $IS_SHARE/system/log after migrating to ICM 7.10.41.10-LTS.

If a WA-*.log file exceeds the configured webadapterAgent.requestLog.chunkSize value, only the first chunk is transferred. As a result, affected WA-*.log files are transferred incompletely, and the original files remain in the $IS_LOCAL/webadapter/log directory. 

This article outlines a workaround and a custom fix for customers using ICM 7.10.

Problem

Starting with ICM version 7.10.41.10-LTS, the WA-*.log files in $IS_LOCAL/webadapter/log are no longer deleted as expected. Additionally, the corresponding files in $IS_SHARE/system/log are incomplete. Only .part files are visible, all with the same file size, but none of them contain the full log content.

Solution

There are two options available to resolve this issue.

Option 1: Increase chunkSize 

Increase the webadapterAgent.requestLog.chunkSize property in the global webadapter.properties file to a value larger than the typical size of the WA-*.log file (e.g., webadapterAgent.requestLog.chunkSize=100000000 for 100MB). This change should be applied during deployment.

For detailed instructions, refer to Cookbook - Deployment Tools ICM 7.10 (Recipe: Change Deployed File Content With Filters).

Option 2: Apply Custom Fix (Recommended)

A custom fix for the Web Adapter Agent is available for ICM 7.10.41.10-LTS. It can be downloaded as a ZIP archive:

• webadapteragent_7.10.41.10-LTS.zip

Extract and use only the included JAR file and apply it during deployment. For implementation details, refer to Cookbook - Deployment Tools ICM 7.10 (Recipe: Custom Fix Deployment).

Alternatively, a preconfigured subproject is available:

• webadapter-local-cartridge.zip

Use the included webadapter-local subproject in your deployment to apply the fix. The updated webadapteragent.jar is already integrated.

Instruction for Using the webadapter-local Subproject 

1. Add the webadapter-local subproject to your root project (webadapter-local-cartridge.zip)
2. Modify the build.gradle file in your <root-project>/<assembly>/ directory to include the subproject during web server deployment:
   

   assembly {
       ...
       hostTypes {
           ...
   +         webserver {
   +             include ( 
   +                 project(':webadapter-local'),
   +             ) {
   +             transitive = false
   +             }
   +         }
       }
   }
