| Summary | 0053918: BO utilization causes excessive JVM metaspace usage | ||
| Revision | 2023-11-14 07:39 by alostale | ||
| Steps To Reproduce | #1. In a real customer In real customers with BO intensive use, monitory metaspace: jcmd Bootstrap VM.metaspace Detected in some live customer having 30GB allocated for heap space, meta to be >5GB. #2. Emulate it by executing this code try { System.out.println("start.,,"); long t = System.currentTimeMillis(); for (int i = 0; i < 10000; i++) { ParameterUtils.getJSExpressionResult(Map.of("inpTableId", "333") // , null, "OB.getFilterExpression(\"org.openbravo.erpCommon.info.BusinessPartnerSelectorFilterExpression\")"); } System.out.println("done " + (System.currentTimeMillis() - t)); } catch (ScriptException e) { // TODO Auto-generated catch block e.printStackTrace(); } |

| Description | When backoffice application is intensively used, the JVM metaspace consumption considerably increases. Javascript code is compiled in the JVM for OBBindings (ie. for filter selectors), causing this pressure in the metaspace. Ie.: this command shows the number of currently loaded scripts, which can be huege: jcmd Bootstrap VM.metaspace show-classes show-loaders | grep org.mozilla.javascript.gen | wc -l |
