========= Dump for incident 404618 (ORA 600 [723]) ========

*** 2026-04-14 08:00:23.341
----- Beginning of Customized Incident Dump(s) -----
******** ERROR: PGA memory leak detected 154120 > 130680 ********
========================================

154120    实际检测到的PGA内存泄漏量，单位是字节
130680    Oracle内部设置的阈值，单位是字节

154120 > 130680    泄漏量超过了阈值，所以触发了ORA-00600错误

换算：    130680 / 1024 ≈ 127.6 KB
        154120 字节 ÷ 1024 ≈ 150.5 KB

=========================================
所以，这个错误的核心就是：某个会话在结束时，有大约150KB的PGA内存没有被正确释放，超过了127.6KB的阈值，于是Oracle报了警。


这是个软件bug，对数据库的使用没有影响，可以通过打最新的数据库补丁，或者升级数据库版本进行处理。
