Hello, Can anyone suggest what the problem is here, please? It sounds like a pretty fundamental issue but I have not managed to find any similar reports (and potential solutions) elsewhere.
Thanks, Mark From: Mark Harris Sent: 18 March 2020 14:51 To: [email protected] Subject: RE: Cannot acquire read lock within x millis I should add that I'm seeing the "Cannot acquire read lock within x millis" messages appear in the logs of both application servers several seconds apart, implying that the two instances are not polling at precisely the same time. Yet neither of them are able to process the file for several rounds of polling before one of them does. Thanks, Mark From: Mark Harris Sent: 18 March 2020 13:55 To: [email protected]<mailto:[email protected]> Subject: Cannot acquire read lock within x millis Hello, I'm encountering the following message in my logs when two instances of a Java application running Camel on separate servers (to ensure HA) are trying to poll an sFTP server to process a file: Cannot acquire read lock within 20000 millis. Will skip the file: RemoteFile[name and path of file on sFTP server] The route URI is like this: sftp://<user>@<server>:<port>/<path>?connectTimeout=120000&delay=60s&delete=true&disconnect=true&ignoreFileNotFoundOrPermissionError=true&inProgressRepository=<repository>&include=<mask>&password=<password>&readLock=changed&readLockMinAge=10s&soTimeout=300000 The process copies the file to a local shared folder where it is further processed by routes running on the same 2 Java applications with a URI like this: file://<path>?delay=60s&inProgressRepository=<repository>&include=<mask>&readLock=changed&readLockMinAge=10s<file://%3cpath%3e?delay=60s&inProgressRepository=%3crepository%3e&include=%3cmask%3e&readLock=changed&readLockMinAge=10s> ... where I also get the same message: Cannot acquire read lock within 10000 millis. Will skip the file: GenericFile[name and path of file on shared folder] Eventually the file is processed but it is taking several polls before one of the applications processes the file, leading to delays. Can anyone advise what the issue is and how I can fix it, please? I'm using Camel v 2.24.2. Thanks, Mark
