VastBase数据库Crash后使用gdb收集coredump信息
🐘 数据库版本：VastBase G100 V3.0.8
检查数据库崩溃后生成的core文件：
[vbdba@dbhost vastbase]$ ll -h core*
-rw------- 1 vbdba vbdba 62G Aug 20 20:02 core-vastbase-162199-2025_08_20_19_57_57-bbox.lz4
-rw------- 1 vbdba vbdba 19G Aug 21 10:38 core-vastbase-290510-2025_08_21_10_36_30-bbox.lz4
解压缩core的lz4文件：
yum install -y lz4 lz4-devel
cd /vastdata/vbdba/vastbase
lz4 -d core-vastbase-162199-2025_08_20_19_57_57-bbox.lz4
lz4 -d core-vastbase-290510-2025_08_21_10_36_30-bbox.lz4
示例：
[vbdba@dbhost vastbase]$ lz4 -d core-vastbase-162199-2025_08_20_19_57_57-bbox.lz4

[vbdba@dbhost vastbase]$ ll -h core*

gaussdb: /vastbase/app_3.0.8_psu2_26989/bin/gaussdb
使用gdb调试解析core文件：
whereis gaussdb
gdb /vastbase/app_3.0.8_psu2_26989/bin/gaussdb core-vastbase-162199-2025_08_20_19_57_57-bbox
gdb /vastbase/app_3.0.8_psu2_26989/bin/gaussdb core-vastbase-290510-2025_08_21_10_36_30-bbox
示例：
[vbdba@dbhost vastbase]$ gdb /vastbase/app_3.0.8_psu2_26989/bin/gaussdb core-vastbase-290510-2025_08_21_10_36_30-bbox
