This works as follows 1. To maximize performance, optimize memory allocation patterns to minimize the frequency of gc events, thereby reducing time spent on the slow path. Give them a warm welcome. Switching to g1gc is a common solution in spark jobs, but as youve noticed, dlt clusters especially serverless or managed job clusters don’t expose options to change jvm, This typically leads to oome in the affected threads. The error message retried waiting for gclocker too often allocating 12488753 words in java typically indicates that the java virtual machine jvm is experiencing issues due to large. Here is an attempt to simplify gclocker implementation for serial and parallel, The common pattern is that a gc lockerinitiated young gc happens, Gclocker initiated gc：如果线程执行在 jni 临界区时，刚好需要进行gc，此时 gc locker 将会阻止 gc 的发生，同时阻止其他线程进入 jni 临界区，直到最后一个线程退出.

使用本地方法jni函数访问jvm中的字符串或数组数据（代码在临界区执行），必须保证原始数据不被修改，防止其它线程的操作、或发生gc回收改字符串对象。 利, 6 the jvm triggered a gclocker initiated gc minor collection and rescheduled the thread attempting the object allocation. But for me in practice, au pause of 4 sec 480 ms due to gclocker initiated gc is bringing the server down and is a fairly bad outage. Sets the java heap occupancy threshold that triggers a marking, , calling jni critical apis. 业务背景某个java业务应用，所有容器实例minor gc频繁，major gc偶发，每天重启一次。 现象是业务每隔30分钟会从商品域拉取全量商品和sku数据，更新到缓存中。.

Gclocker initiated gc 是由 jvm 的 jni 本地代码（如通过 directbytebuffer 分配的本地内存）触发。 在某些情况下，本地代码可能通过 jni 保持 gc 锁，阻止垃圾回收器回, Solution verified updated.
